Listen Up! Toxic Chinese Drywall Creates Housing Risk

Along the Gulf Coast and across the country, it's being called a "silent hurricane." Between 2004 and 2007, an estimated 100,000 homes in more than 20 states were built with toxic drywall imported from China.

Emissions from the drywall corrode plumbing and electrical systems. Homeowners also blame them for headaches and respiratory ailments. Replacing Chinese drywall in the United States could cost $15 billion to $25 billion, according to National Underwriter, an insurance industry publication.
